getting the memo

Last night, we went to a friend's wedding reception. About 30 minutes before when we had to leave, I started rummaging around looking for a suit, tie, and nice shirt - all those pieces of clothing that rarely get used. I tried to get some advice on tie/shirt matching over IM from a friend. Finally, frustrated, I decided that I was just going to wear a Kurta instead. I have some Kurtas from the various ceremonies surrounding our wedding - and they never see the light of day anyway. I picked a nice white one with a bit of embroidery on it.

We showed up at the hotel and proceeded to grab a drink and appetizers. I didn't see anyone else wearing a kurta. About 45 minutes into the event, I was pretty distraught; whereas the women were decked out in their finest Indian clothes, I stood alone, in bright white, in a sea of black suits.

It's as if everyone else there got the memo, but they forgot to cc me.

You'd think more people would wear Indian clothes at an Indian wedding, huh? But maybe evening events call for a suit.

So what does one do in a situation like that? I did what any self respecting male does. I downed my wine, took a few gulps of scotch, and used all that liquid confidence to pretend like *they* hadn't received the memo.

I'm penning this for posterity, lest all the liquid confidence makes me forget to wear a suit next time.

Socio-adjusting

Babies have this comfort zone of how many people they want to be around. If they grow up with lots of people around, they suddenly feel at a loss when they are alone. If they are used to just having their parents around, they feel overwhelmed when they are around many people for a long time.

I've noticed it with many 2nd generation indian kids who go back to India on vacation. They flip out when they first get there, because they're suddenly being doted on by grandparents, uncles, aunts, and cousins. Three or four weeks later, they head back home and are suddenly antsy when only their parents (and maybe siblings) are around.

I think that happened to me this month. I've been working alone for the past nine months and was suddenly thrust into three weeks of meeting people (though I actually didn't do the normal amount of socializing because I was pretty busy working).

Now I'm back in Berkeley, and working from an empty, quiet home again seems awfully difficult.

not another rails post

It has come to my attention that many of my readers couldn't care less about rails. I apologize. Since this past february, my life has been consumed by reporterist. I eat, breathe, and dream about it. Bed-talk with my wife often involves reporterist brainstorming.

And yet, life does tend to have a way of going on. I'm currently spending a few weeks in Pune, and am fortunate to be able to attend the famous Sawai Gandharva Mahotsav - a four-day indian classical music festival. It's my first ever, and the first day was great!

I'm happy to report that eighteen months of living in Bangalore seems to have solidified my India-driving skills. I'm now pretty comfortable driving here even after not doing so for a year.

I got a wisdom tooth removed, and have been in pain for over a week. Earlier this week I decided to stop taking painkillers, and start drinking instead. A bit of cognac from Dad's bar seems to have eased the pain (and pleased the palette) this evening.

testing mailers in rails

AFAIK, the only way to test mailers is to create a mail object directly, and then look for textual matches within the mail body.
That's lame. I wanted something more akin to the 'template_objects' method that you can call on a response when writing functional tests.

Turns out that ActionMailer::Base does some funky stuff that makes it really hard to do this. Here's what I resorted to in the mean time:

Let's say that my NotificationMailer looks something like:

class NotificationMailer < ActionMailer::Base
 def my_notification_method
  @body['name'] = "bob"
 end
end

add the following code in test_helper.rb:

ActionMailer::Base.class_eval {
  alias initialize_which_results_in_auto_create initialize
  def initialize( method_name = nil, *params )
    return if( :test == method_name )
    initialize_which_results_in_auto_create( method_name, *params )
  end

  class << ActionMailer::Base
    def grab_vars( method, *params )
      obj = new(:test)
      obj.send( :initialize_defaults, method )
      obj.send( method, *params )
      return {:body => obj.body, :subject => obj.subject, :recipients => obj.recipients}
    end
  end # class
}

I can now check for 'assigns' as follows:

nm = NotificationMailer.grab_vars( :my_notification_method )
assert_equal( "bob", nm[:body]['name'] )

That's still fugly, but it lets me test the @body hash at least. If you have a better way of doing this, or a way to make that look prettier, please let me know!

Rails Integration Testing

I found this to be a pretty good (well, there's not really much info out there) intro to writing integration tests.

But if you look in the comments, people are sort of stumped on how to deal with logging in users when you don't have passwords stored in the clear.

Here's my solution, which injects the user object directly into the request session, meaning that you don't need any other ugly hacks (such as letting your user controller accept hashed passwords.. ugh).

# http://weblog.jamisbuck.org/2006/3/9/integration-testing-in-rails-1-1
# describes some cool integration testing, but there's no
# solution for how to 'inject' a user into the system when all 
# you have is hashed passwords.
# The code below lets you inject a user object directly into your
# 'session' object.

# So you can add the following methods to your integration test (see the above blog
# for more explanation):
#
#   def new_session_as( user )
#     new_session do | sess | # new_session is defined per the blog post above
#       sess.user_object = user # aha this is where we inject the user object
#       yield sess if block_given?
#     end
#   end


# allow a user_object to be injected via the HTTP headers
ActionController::Integration::Session.class_eval {
  attr_accessor :user_object
  alias process_without_user_headers process
  def process( method, path, parameters=nil, headers=nil )
    unless self.user_object.nil?
      headers = (headers || {}).merge( {'X_USER_HACK' => self.user_object } ) 
    end
    process_without_user_headers( method, path, parameters, headers )
  end
}

# extract the user object from the headers, and store it as an attribute
ActionController::Integration::Session::MockCGI.class_eval {
  alias initialize_for_real initialize
  attr_accessor :user_object
  def initialize( env, input )
    user = env.delete( 'HTTP_X_USER_HACK' )
    self.user_object = user
    initialize_for_real( env, input )
  end
}

# extract the user object from the mock cgi class, and 
# set it up in our session
ActionController::CgiRequest.class_eval {
  alias initialize_for_real initialize
  def initialize( cgi, options )
    initialize_for_real( cgi,options )
    # The following line may be different for you:
    self.session['user'] = cgi.user_object
  end
}

reporterist.com private beta

So we just officially launched a private beta of reporterist to 60 professional journalists.
We just launched a very, very small subset of our functionality - just to get some initial feedback from our users.

I'm super excited (and nervous).

You can follow the reporterist blog for more updates.

In other, more personal, news; we found an nice apartment in Berkeley (not the easiest of things to do) and have begun to settle in. Our neighbours are awesome - three of the wife's classmates actually stay next door.

That's all for now.

amazon fps launched!

This is very exciting! The Amazon Flexible Payments Service has finally launched!

I say finally, because I had the honor to be a small part of the development of this service when I moved to Bangalore. Amazon FPS was built almost entirely out of India by a really awesome team.

I left that team in February 2006, so I can't claim that much of my code lives on (which may be a good thing!) but I'm definitely proud to have played a part.

Awesome job guys!

update: here's the aws blog post.

figuring out the gmail spam filters

So I'm working on a web application, and today I was trying to send invites out to some users. Turns out that they were going into the gmail spam filter.

I made sure that my RDNS (Reverse DNS) was set up correctly, and then I checked the email headers to ensure that gmail didn't suspect my ISP's IP address as a spammer IP.

A friend suggested that it might have something to do with the content of my emails, and not the body.

So I started playing around and, sure enough, that was it. After several emails I realized that it had to do with the link I was sending in the email. At first I thought that it might have to do with the length of the link (and an MD5-encoded token in the params).

After several tests I figured out exactly what trips it: If I send email from a foo.com server (hostname = foo.com, DNS and RDNS consistent with foo.com) with a signup link for foo.com, then that sends the mail to spam. If, on the other hand, I send email from a bar.com server with a link to foo.com, then the email makes it through the spam filter.

That seems so non-intuitive to me. It seems more shady for an email from bar.com to have a link to foo.com in it.

Anyways, I've got a temporary work-around (I think?), but I still don't know the 'right' way do this.

music for the soul

At most points in my life, I've listened to, sang, played, and loved music that 'spoke' to me. I think most people know what I'm talking about.

Sadly, there have been some points (more so recently) when I just haven't been able to find music that speaks to me. Much of my music collection just doesn't do it for me anymore. Even classic evergreens like U2 and Bob Dylan - which usually always have something to say to me - just fall on my ears but don't penetrate any deeper.

Those who know my general music taste; feel free to recommend me some new music.

The quest for quarters

It's been a while since I needed quarters to do laundry.
In Seattle, we had an in-unit washer/dryer, and in Berkeley we could send money from a student account directly to the machines.

In Baltimore, I we need quarters for laundry and, having just moved here, I don't have a jar full of them lying around. Of course, I waited until the last possible minute to do laundry. So yesterday I rolled out of bed and decided to go in search of quarters. The wife had the car, so I was limited to walking distance.

I started with the local mini-mart; he agreed to give me 4 quarters but no more. Next I went to the laundromat. The lady there was exceptionally rude and gave me a "yeah right" when I asked if she had quarters. She wasn't very helpful telling me about banks in the area either. My next stop was a few blocks away at a laundromat with a change machine; turns out that it had been broken for years. I went into another minimart, and the desi owner refused me quarters even if I were to buy something.

I finally gave up and came home. On rummaging through my suitcases, I was able to find one hiding undergarment, thus allowing me to shower.

In the evening when the wife got home, we went to the gym and decided to stop by a grocery store afterwards. We happened upon a small stripmall with a laundromat and pharmacy, so we stopped there.

As I was about to put my $20 bill into the change machine at the laundromat, I simultaneously heard a raspy voice and read the hand-scrwaled notice in front of me: "No change unless you're doing your laundry here!" I apologized and walked out, frustrated.

At the RiteAid, we purchased our wares, and politely (maybe desperately?) asked for a roll of quarters. She didn't have a roll, but gave us a few dollars and suggested that we ask the other cashier.

As we were about to ask the other cashier for change, the lady in front of us says to her daughter as she's walking away "ok. well, I think not we shold have enough for one more load."
The cashier was out of quarters.

I feel like we've entered the quarter-free twilight zone. Maybe this weekend we'll drive down to DC or Virgina and smuggle a few rolls of quarters over the border. Who knows, maybe we could sell them for a premiuim.

Multimedia Storytelling: Spring New Media Lecture Series

oops. I meant to post this here instead.

roller coaster

Wow.

I had heard about how starting a company can be an emotional roller coaster. But it's been interesting to experience it first hand over the past 3 months. Every good customer response makes me feel on top of the world, and every time I think about all of the things that could go wrong, I start a downward spiral.

And I've barely just started! I'm sure it will become even more challenging once the stakes get higher.

I'm glad I'm not in it alone. Having someone else working on it is great - not only to get things done, but to smooth out the roller coaster, and to help in making judgment calls.

emacs love

I was working on some ruby code just now. I had a hash with keys that were capitalized words, such as:

comp << l['Address'] unless l['Address'].empty?
comp << l['City'] unless l['City'].empty?
comp << l['State'] unless l['State'].empty?
comp << l['Zip'] unless l['Zip'].empty?
comp << l['Country'] unless l['Country'].empty?

but I made some changes so that all of the keys would now be lowercase and turned into symbols. Basically I wanted the output to look like this:

comp << l[:address] unless l[:address].empty?
comp << l[:city] unless l[:city].empty?
comp << l[:state] unless l[:state].empty?
comp << l[:zip] unless l[:zip].empty?
comp << l[:country] unless l[:country].empty?

With a little help from an ex coworker's blog, I was able to achieve this using the following regular expression:

M-x replace-regexp
 l\['\([A-Z]\)\([^']*\)'\]
 l[:\,(downcase \1)\2]

Note that the '\,' (backslash-comma) combination escapes the lisp command that is part of the replacement text.
I never ceased to be amazed by the power of emacs. I'm still decades away from being able to develop a webservice in lisp. :)

juice

I just received a juicer - the Breville JE95XL Two-Speed Juice Fountain Plus - from amazon. It's pretty sweet. I just made some carrot/celery/ginger juice. The leftover pulp is moist but not soggy - so it seems to have done a good job extracting. I'm going to see if we can bake the pulp into something though instead of wasting it.

The fire is burning.

Several people have asked me if I have a hard time motivating myself now that I'm starting something of my own. In fact, that's a question I asked my friend (and bluedot founder) a few months ago.

The answer is an emphatic no. I have this hot fire burning under my rear end that makes me do all sorts of odd things. Like wake up at 4:15am to start coding because I just dreamed up (literally) a line of code. Or pass on the wonderful california sun and sit inside and code all day.

I realized today that my first code-complete deadline is in about 15 weeks. And that just turned up the temperature a notch. The only redeeming thought is that what I have so far is only 6 weeks worth of actual coding.

eating whole and cheap

The wife is doing a story (possibly series of stories) on eating whole/ natural/ organic/ healthy on a low budget and without devoting your entire day to cooking (I'm busy coding all day, and she's busy with classes and assignments). We also live in a tiny studio with two hotplates, one bowl, two pans - you get the point - a minimalist kitchen.

This week we are on a $60/week food budget for the both of us.

My breakfast today was fig-bran muffins that she made (basic recipe courtesy our buddy guidoism) and a big strawberry/banana milkshake. For lunch I had a sandwich with guacamole (home-made), hummus (store-bought), yogurt (store-bought), cheese, tomatoes, and bread (store-bought). Dinner was lentil soup, asparagus, and bread. I want to try making my own hummus next.

I think we still have a few bucks left on our $60 budget, surprisingly, and a lot of ingredients with which to cook the rest of the week.

She hasn't yet decided how long this experiment will last. Part of me wants to continue with it for a while - just so I eat healthier and more creatively. The rest of me is hoping the budget will increase a little :)

Magnifying mirrors

I've had this hunch for a while about people that really get on my nerves. The hunch is that the people that irritate me are the people in whom I see my bad qualities qualities reflected or, more often, magnified.

I wasn't sure about it but a few weeks ago the wife and I sat down and talked about all of the people that annoy each of us (both of us are pretty chill, if I may so say so myself, so the list was quite short - but both of us have a few people that drive us up the wall). We realized that, in each case, the thing that gets on our nerves about the person is some trait that we both are very conscious of in ourselves and try to change or improve.

So all of a sudden getting irritated by someone has a silver lining - it's just a little reminder about the things that we need to work harder on improving about ourselves.

I'm curious - have you found the same to be true in your experience?

Update: The wife claims that she came up with the idea long ago and I have just misappropriated it from her. The wife is always right.

road trip

All of our belongings are now in a 17' U Haul, and we will be hitting the proverbial road shortly, to head for sunny California. Goodbye, Seattle. We'll miss you.

functional tests

The first time I played with rails (two years ago), I was super sloppy about writing unit tests for my models - I wasn't working on a very complex product.

This time, I've been very diligent about writing unit tests - and it has definitely paid off.

Since my application structure is still in flux, though, I haven't written a single functional test. SO far, so good. But now it's getting to the point where things are just starting to blow up a little at a time. Which goes to show that any shortcuts you take in life will come bite you in the ass sooner or later.

So now I need to temporarily stop working on refining the product and go back and get myself up to speed on how to write functional tests, and start writing tests for all of the stuff I've done so far. Once I get over the initial inertia, adding new tests, and refactoring them as the application changes should be actually quite easy.

Better now than after I have customers, I suppose :)

Good old music

A few years ago when I got my iPod, I decided not to import all of the random mp3s that I had from college - mainly because they came from various sources and didn't have all the ID3 tags in a consistent format.

So I started by importing the CDs that I owned, and slowly grew my collection.

Eventually, I moved all those mp3s off onto a backup drive and forgot about them.

Then, the other night, I remember that I had a live recording of a U2 song - and I hadn't heard it in ages. So I found that stash of mp3s and started importing a lot of that music into iTunes; fixing up the ID3 tags as I went.

And now I have all this great music from when I was in college and high school and it's bringing back wonderful memories. What a gift.
